In a medium skillet, whisk together all of the ingredients (except the meatballs and scallions). Heat over medium heat until boiling. Reduce heat and whisk until sugar is dissolved. Taste for sweet/heat balance. If you like it sweeter add more brown sugar, 1 tbsp at a time. Add additional sriracha or hot sauce for more heat.

Stir in All Purpose Meatballs. They can be frozen or thawed. Heat over med-low, stirring occasionally until meatballs are heated through.

Serve over rice or alongside veggies. Or simply serve as an appetizer on their own. Garnish with chopped scallions.
